use the remainder theorem to find the remainder when p(x)=x^4-9x^3-5x^2-3x+4 is divided by x+3

Step-by-step explanation:

I think the answer is 5x

292

Step-by-step explanation:

We can change x+3 to x=-3 and put that into the polynomial:

(4)+((-3)^4)+(-9(-3)^3)+(-5(-3)^2)+(-3(-3))=

(4)+(81)+(243)+(-45)+(9)=

292. That’s the remainder.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
